LncRNA NEAT1 Knockdown Alleviates Lipopolysaccharide-Induced Acute Lung Injury by Modulation of miR-182-5p/WISP1 Axis.
Article in Biochemical genetics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Accumulating evidence has demonstrated the vital roles of long non-coding RNAs (lncRNAs) in acute lung injury (ALI). In this study, we aimed to explore the effect of Nuclear Paraspeckle Assembly Transcript 1 (NEAT1) on ALI development. The ALI mice and cell models were constructed using lipopolysaccharide (LPS)-induced method. The concentrations of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) were measured by enzyme-linked immunosorbent assay (ELISA). The levels of TNF-α mRNA, IL-6 mRNA, IL-1β mRNA, NEAT1, miR-182-5p, and WNT-inducible secreted protein 1 (WISP1) mRNA were determined by quantitative real-time polymerase chain reaction (qRT-PCR) assay. Cell viability was evaluated by Cell Counting Kit-8 (CCK-8) assay. The level of lactate dehydrogenase (LDH) and the activity of caspase-3 were measured by specific kits. The interaction between miR-182-5p and NEAT1 or WISP1 was investigated by dual-luciferase reporter and RNA immunoprecipitation (RIP) assays. Protein levels were measured by Western blot assay. NEAT1 level was elevated in LPS-induced ALI mice and LPS-stimulated MH-S cells. LPS treatment repressed MH-S cell viability and promoted apoptosis and inflammation, while NEAT1 silencing restored the impacts. For mechanism analysis, NEAT1 was identified as the sponge for miR-182-5p to positively regulate WISP1 expression. Moreover, NEAT1 knockdown could accelerate cell viability and inhibit cell apoptosis and inflammation in LPS-induced MH-S cells by elevating miR-182-5p and decreasing WISP1 in LPS-exposed MH-S cells. In addition, NEAT1 deficiency blocked the activation of NF-κB pathway caused by LPS in MH-S cells. NEAT1 overexpression restrained cell viability and facilitated cell apoptosis and inflammation in LPS-exposed MH-S cells through miR-182-5p/WISP1 axis.
